The Companions are a group of warriors who take on private and public contracts for the people of Skyrim, and who purportedly carry on the tradition of the Five Hundred Companions of Ysgramor. It fulfills the same role the Fighters Guild does in other parts of Tamriel. They are based in the city of Whiterun, within the mead hall Jorrvaskr. The most elite members are included in the Circle of Jorrvaskr, and the chief councilor and arbitrator is known as the Harbinger, after Ysgramor, the "harbinger of us all" and the only real recognized leader of the Companions. Each new Harbinger is chosen by the last.
